Application met June 15,1908. serial No. 438,556.

county of Allegheny and State vof Pennsyl-y vania, have invented a newand useful Improvement in Ventilatore; and we do here? by declare thefollowing to be a full, clear, and exact description thereof.

Our invention relates to ventilators, vand has special reference toventilators adapted to be used in connection with the lower rail of awindow-sash.

' The object of our invention is to provide a cheap, simple andefficient ventilator for use between the under surface of the lower railof the window-sasl1 and its frame which will be adjustable for theamount of air fed to the room or apartment, or for the closin olf of thesame, will be adjustable to fit di ferent sized window openings, and canbe locked in the window frame, if desired.

Our invention consists, generally stated, in the novel arrangement,vConstruction and combination of parts, as .hereinafter morespecifically set forthand described and particularly pointed out in theclaims.

. To. enable others skilled in the art to which our invention appertainsto construct and use our improved ventilator, we will describe the samemore fully, referring to the accompanying drawing, in which- Figure 1 isa face view of our improved ventilator showing the same in position inthe window opening. F ig. 2 is a rear view of the ventilator. Fig. 3 isa cross-section of the saine onltheline 3-3 F ig. 2. Fig. 4

is a rear view showing another form of the' ventilator. Fig. 5 is a .toview of the same. Fig. 6 is a cross-section on the line 6 6 Fig. 4. Fig.7 is a detail view.

Like symbols of reference herein indicate like parts in each of thefigures of Athe drawthe end walls 4, 4 fitting against the end edges ofthe same, and connected to the body l which forms the rear wall of saidtrough.

The body portion l is provided witha series of Openings 5, preferably intwo longitudr' nal rows, and the openings in one row are 'body and platerespectively and intothe beveled, as at\ 9. The upper beveled e` ge 9 onthe plate 8 fits within alike shaped guide 10 formed in a strip l1secured on the inner face of the body-1 and vin one 0f the end walls 4of the trough 2, while the lower beveled edge 9 on said plate fitsagainstand conforms tothe inner face-of the inclined front wall 3 of thetrou h .2 and also fits within a like shape gui e 10 in said end wall.4. The inner end of the sliding cover plate 7 within the trough 2, isadapted to engage with the inner face of 4 in order to limit or stop thesaid plate in its inner movement to lclose the openings 5 in the body l,and the outer end of said plate extends throu h said trough to form -ahandleportion an is adapted to.' engage with a stop 12 on said body inits outer movement to open said o enlngs. A knob or handle 13 is securedto t e handle' portion end of the cover plate 7 for moving the saine andclosing of the openings .i ate is provided with-aseries.,

in. the openinor 5, and said pl of openings 14 therein for registeringwith said openings 5 in the openlng of the same,

vsaid Aopenings 14 being of a size similar to said openings 5 and beingarranged 1n like manner as said openings 5. a

The use and operation of our improved ventilator A is as follows Theventilator A is adapted to be placed in the window 'opening a and underthe lower rail 0 of the sash b, so that it is confined between theunderface of said rail and the sides and bottom of the window frame dforming said opening, and in order to snugly fit said ventilator withinsaid opening, the end or ends ofthe body 1 of the same can be sawed 0Eso that'said ends will engage the sides of.

the framed in forming said opening. When the ventilator A is thus inlace thesliding cover plate 7 can be pulledJ out so that its outer-endcomes a ainst the stop 12 on the body 1,`which' 'wi-l allow thel freeentrance the end wall of air through. the openings 5 and 14 linsaidtrough 2, from which it will be Vrletlecfted upt wardly by theinclined wall 3 on said trough and enter the room or apartment, while atthe same time the entrance of dirt through said openings into said-trough and room or apartment is prevented by the screen 6 over theopenings 5. The amount of air entering the openings 5 and 1e into thetrough 2 and room or apartment can be regulated by the position of theplate 7 in the trough 2 with relation to the openings in the. same tothose in the body 1, so that the required amount of air can pass throughsaid openings, and in order to close on' the air passing through saidopenings the plate 7 can be pushed inte the trough so that said plate isin its closed position by its inner 'end coming in contact with the endWall L1 of' said trough.

it' desired, the beveled edges t) of the cover plate '7 can be cut awayat the outerv end or' the saine, as atti, in order to form stops 12 t'oengage with the inner face of the end wall l on the trough in theoutward movement of said plate, and thereby do away with the stop 12 onthe body l, and in order to loclr the ventilator A in its positionwithin the window opening a, a lever cainil can be secured by the screw16 on one end of the body l, as. shown in Fig. 1, for engaging with theside of the frame Z forming said opening.

in case it is desired to forni the ventilator n adjustable with relationto various sizes of window openings, means are provided such asis shownin Figs. e to Y, in which the body i of the ventilator can preferably beformed of sprirnr metal and adjacent to the end walls e, d or' thetrough 2 said body can terminate in the pointed or inclined ends i?, andthe upper and lower side edges or' body provided with lips 18 thereon. Asliding end portion i9 having a groove 2() inthe upper and lower edgesof the same is connected to the body l through the lips 18 thereonfit-ting in said grooves and-forming therewith a guiding slidableconnection, and the inner ends et said portions have a longitudinal slot2l Within. the same to permit the air to pass into the trough 2 and roomor apartment through the openings 5 and 14 in said body and plate 7,respectively, when said portions provide for a small size ventilator orwhen drawn out to form a iarger ventilator, in which lcase the ends 17will prevent any airfpassing into the room or apartment by closing upthe openings formed by said slots. V

1t will be evident that our improved ventiiator can be used in and aspart of the rails or the sash, and various other modications andehangesin the design and construction of our improved ventilator may beresorted l to withoutdeparting from the spirit of the erases inventionor sacrificing any of its advan` tages. y

it will thus be seen that the parts of our improved ventilator can beformed of any suitable material such as metal or wood and can bearranged to tit any size of a'window opening and securely held therein.It will prevent the entrance of ies or insects into the roon'i orapartment, will be draftless, and at the saine time admit the amount et'air desired into the room or apartment. it contains few and simple partsand will not be liable to get out of order, stick, Warp or break, whileat the saine tinie it can be easily operated and applied for almostinstant use by any unskilled person, without the necessityof changingits parte, or the vsash or frame to which it is to be connected andused.

What we claim as our invention, and desire to secure by Letters Patent,is

l. A ventilator comprising a body portion having openings within thesaine, a box extending out from the inner tace of said body and havingan inclined front wall, and a sliding cover plate in said box havingopen-I ings therein for registering with the openings in said body andprovided With beveled side edges for engaging with a like shaped guideon said body and with said inclined wall.

openings therein for registering'with the.

openings in said body and adapted to engage by one end with the end ofsaid box to limit the inward movement of the same, said plato having ahandle portion at its other end extending through said box and havingintegral stops formed on the side edge or' said end by cut away portionsthereon for en gaging with the other end of said box to limit theoutward movement of said plate.

3. ventilator for window and other like trainee, comprising a bodyportion having openings within the same, means for opening and closingsaid openings, slidable end portions on said body having slots thereinfor permitting the free entrance of air through said openings, and endortio'ns on said body for closing the space termed by`said slots whensaid slidable portions are drawn out.

in testimony' whereof, we, the said Animar B.. STUTZ and CHARLES M.lGnL, have hereunto set' our hands.
